Genshin Impact.

In the vast world of immortals, Lin Feng and Li Er embarked on a journey to the mortal world to experience disasters. Their figures were like a bright light, cutting through the mist of the mortal world.

Lin Feng is a handsome and elegant young knight with extraordinary temperament. His eyes are shining with a firm light, as if they can penetrate all darkness. He is dressed in a white robe, with a sharp sword on his waist. The scabbard is inlaid with dazzling gems, emitting a mysterious light. Lin Feng has powerful immortal power, and his swordsmanship is superb, able to kill the enemy in an instant. However, he knows that his immortal power is not strong enough, and he needs to hone himself and improve his strength by going down to the mortal world to experience tribulations.

Li'er is a beautiful, gentle and kind woman. Her long hair falls on her shoulders like a waterfall, and her eyes are full of tenderness and intelligence. She wears a light blue dress, and the hem of her skirt flutters in the wind, like a fairy descending to the earth. Li'er is good at magic, and her magic can heal injuries and bring hope and warmth to people. She descended to the earth with Lin Feng to experience tribulations, not only to improve her own strength, but also to accompany Lin Feng and face all challenges together.

During their journey, a mysterious old man appeared. The old man had white hair, a kind face, and deep wisdom in his eyes. He was dressed in a gray robe and held a cane in his hand, which was engraved with mysterious runes. The old man was an experienced immortal who knew the dangers and opportunities of descending to the mortal world. He decided to help Lin Feng and Li Er and guide them on the right path.

They came to a mysterious valley, which was filled with thick fog, making it difficult to see the road ahead. Lin Feng walked carefully in front, holding the sword tightly in his hand, and vigilantly observing the surrounding environment. Li'er followed closely behind Lin Feng, performing magic in her hands to illuminate the road ahead for them.

Suddenly, a gust of wind whistled past, and the fog dissipated instantly. They found themselves in a huge maze, the walls of which were engraved with mysterious runes and patterns. Lin Feng frowned, knowing that this maze must be hiding a huge danger.

"Be careful, this maze may have traps." Lin Feng warned.

Li'er nodded, and she cast her magic to try to sense the danger in the maze. However, her magic seemed to be interfered by some force and could not be cast normally.

"My magic has been disturbed. There must be a powerful force here trying to stop us." Li'er said.

The old man smiled slightly. He waved the cane in his hand. A flash of light passed by, and the runes and patterns in the maze began to flicker.

"This maze is an ancient immortal formation. Only by finding the center of the formation can we break it," said the old man.

Lin Feng and Li Er looked at each other and decided to find the center of the formation together. They carefully shuttled through the maze, avoiding various traps and dangers. In the process, they encountered many strange creatures. These creatures had powerful powers and brought them great challenges.

Lin Feng brandished his sword and started a fierce battle with these creatures. His swordsmanship was as fast as lightning, and each sword could accurately hit the enemy's vital points. Li'er performed magic to support Lin Feng. Her magic could heal Lin Feng's wounds and keep him strong.

During the battle, Lin Feng gradually learned some new sword skills. He found that he could inject immortal power into the sword, making the sword more powerful. He began to try to use this skill to fight more fiercely with the enemy.

After a hard battle, they finally found the center of the formation. The center of the formation was a huge crystal ball, which exuded powerful immortal power. Lin Feng approached the crystal ball carefully, trying to use his immortal power to break the formation. However, the moment he touched the crystal ball, a powerful force bounced him out.

"Be careful, this crystal ball contains powerful power and cannot be touched easily." said the old man.

Lin Feng stood up, wiped the blood from the corner of his mouth, his eyes full of determination.

"I must break this formation and continue our journey of tribulation." Lin Feng said.

The old man nodded, and he began to instruct Lin Feng on how to use his immortal power to break the formation. Under the old man's guidance, Lin Feng gradually mastered the method of breaking the formation. He injected immortal power into the sword, and then stabbed the crystal ball with the sword. The power in the crystal ball began to gradually weaken, and was finally successfully broken by Lin Feng.

After cracking the maze, they continued on their journey. During the journey, they met an injured immortal. The immortal told them that there was a mysterious mountain not far away, and on the mountain there was an ancient immortal secret book. As long as they got this secret book, they would be able to improve their strength.

Lin Feng and Li'er decided to go to the mountain to look for the secret book of immortal arts. When they arrived at the foot of the mountain, they found that the mountain was towering into the clouds and surrounded by thick fog. Lin Feng used immortal arts to try to dispel the fog, but the fog became thicker and thicker, making it impossible for them to see the road ahead.

"There's something strange about this fog. We have to be careful." Lin Feng said.

Li'er nodded, and she cast a spell to light the way ahead for them. They walked carefully in the mist, and suddenly, a huge monster rushed out of the mist. The monster had sharp claws and sharp teeth, and its eyes were full of ferocity.

Lin Feng brandished his sword and started a fierce battle with the monster. The monster was very powerful, and every attack could cause great damage to Lin Feng. Li Er performed magic to support Lin Feng. Her magic could weaken the monster's power, giving Lin Feng a chance to launch a fatal attack.

During the battle, Lin Feng gradually realized some new magic skills. He found that he could condense the magic power on the sword to form a powerful sword energy that could attack the enemy from a distance. He began to try to use this skill to fight more fiercely with monsters.

After a hard battle, they finally defeated the monster. They continued to move forward and finally reached the top of the mountain. On the top of the mountain, they found an ancient secret book of immortal arts. The secret book exuded a powerful immortal power, which made people feel a mysterious power.

Lin Feng carefully picked up the secret book and began to read it. The secret book recorded many powerful immortal arts skills and cultivation methods, which benefited Lin Feng a lot. He decided to pass on the immortal arts skills and cultivation methods in the secret book to Li'er, so that they could improve their strength together.

In the following days, Lin Feng and Li Er began to practice the immortal arts diligently. They practiced hard every day and constantly improved their strength. In the process of practice, they encountered many difficulties and challenges, but they never gave up and persisted in their beliefs.

After a period of training, their strength has been greatly improved. They decided to continue their journey to the mortal world to find more opportunities and challenges. During the journey, they met many like-minded immortals, and they fought side by side and faced various dangers and challenges together.

As their strength continued to increase, they gradually attracted the attention of some evil forces. These evil forces began to hunt them down, trying to stop them from continuing to improve their strength. Lin Feng and Li Er were not intimidated by these evil forces. They decided to bravely face these challenges and protect themselves and the people around them.

In a fierce battle, Lin Feng and Li Er showed great strength and courage. They used their own magic and swordsmanship to defeat the leader of the evil forces and brought peace and tranquility to the world of immortals.

Their stories spread throughout the world of immortals and became legends among people. Their names were remembered by people and became symbols of bravery and justice.
